Waffenamt stamps with letters are not uncommon, easy ones like WaA80 ring a bell? That's Brünn II, or WaC10 on K43 stocks. How about WaAD20 - on French Pistols? It's hard to believe because you probably don't pay close attention to anything that isn't sniper related, that isn't your fault but you just like that stuff, it's impossible to know it all. I have the benefit that I HAD to look at everything, or at least a lot of stuff.
